LM22672EVAL
개요
The LM22672 evaluation board is designed to demonstrate the capabilities of the LM22672 switching regulator. The LM22672 evaluation board is configured to provide an output voltage of 3.3V up to 1A load current with an input voltage range of 4.5V to 42V. Due to the low RDS(ON) of the integrated N-channel MOSFET and maximum duty -cycle limitations, the minimum input voltage of 4.5V will only provide a 3.3V output voltage for load currents up to 500 mA. For load currents higher than 500 mA, an input voltage of 5.5V or higher is required. The typical operating frequency is 500 kHz. The evaluation board is designed to operate at ambient temperatures up to 50 °C.
특징
- Input Range: 4.5V to 42V
- Output Voltage: 3.3V
- Output Current Range: 0A to 1A
- Frequency of Operation: 500 kHz
- Board Size: 1.5 X 1.5 inches
- Package: PSOP-8
At low input voltages between 4.5V and 6V, a minimum load of approximately 5 mA may be required to reach a regulated 3.3V output voltage. To aid in the design and evaluation of DC/DC buck converter solutions based on the LM22672 switching regulator, the evaluation board can be re-configured for different output voltages.
